Minnewanka Lake is the only lake in the Banff National Park where motor boats are allowed, and does look like a really nice place to take your boat out for the evening to watch the stars from. But I don't have a boat. Some sheep were crossing the street just as I was leaving the car park.
Two Jack Lake is very pretty, extremely idyllic and calm, and looks like a great spot to picnic or for a little paddle. But keep a watch out for the wildlife! Elk all around while I was there.
The nearby Jackson Lake is a little further off at the end of a cul-de-sac and seems rather popular among hikers. I've heard that the trail around the lake is good for wildlife sightings, although we did not have time to explore much.
